TECHNICAL FIELD

The present invention relates to a wireless battery snap, particularly,one for use in an electrical device for connecting a battery.

BACKGROUND OF THE INVENTION

A cylindrical shape rather than a rectangular shape battery is normallyused in an electric device as the power supply. One of the reasons beingthat the electrical wires which protrude from the battery snap make itinconvenient for use. From a technical point of view, the electricalwires which protrude from the battery snap now available in the marketmay be twisted, stretched and disconnected during use which affect theconductivity of the battery snap. The cylindrical plug and the batterysnap socket are exposed and may result in a short circuit causing damageto the electrical device and may result in injury to the user.Generally, a switch for controlling the power supply has to be added tothe electrical device.

SUMMARY OF THE INVENTION

The Technical Problem to be Solved

To overcome the limitation of the types of battery that can be used inan existing battery snap, the inconvenience of using a battery snap withprotruding electrical wires, exposing the cylindrical plug and batterysnap socket which may result in a short circuit as well as the additionof a switch for controlling the power supply, the present invention iscreated without any protruding electrical wires, which can greatlyimprove the safety and expand the application of different battery typesin use without the need of a switch to control the power supply.

The Technical Solution for Solving the Technical Problem

The wireless battery snap in the present invention comprises of aninsulating support, two conductive eyelets, a cylindrical socket and aplug electrode, a conductive spring, a conductive contact plate, aninsulating sheet and an insulating cover. In the insulating supportthere are at least two electrode holes in a formed-shape and a strip ina formed-shape protruding toward the other side and having a slottedbase and side walls for securing the conductive contact plate,conductive spring, the eyelets and insulating cover. The cylindricalsocket and plug electrodes extend through the two eyelets, conductivespring, and the contact plate to be fastened to the insulating support.The insulating sheet is located between the conductive spring and theother eyelet. The battery used is the type that the two cylindricalbutton electrodes are on the same plane.

Two button electrodes of the battery are disposed on the cylindricalsocket and plug electrodes of the wireless battery snap with one of thecylindrical socket and plug electrodes connected to the contact plate bythe conductive eyelets and the contact sheet secured to the flat contactsurface formed in the protruded forming slotted base. Anothercylindrical socket and plug electrode is connected to the conductivespring and contact plate by the conductive eyelets. The conductivespring or contact plate is disposed in the middle position of twoforming electrode holes on the insulating support with the insulatingcover fastened to the insulating support.

In use, it is necessary to provide a contact electrode with twoindependent poles with the two electrodes of the contact electrodeconnected to the other device. The conductive spring or contact plate ofthe wireless battery snap permanently contacts and depresses on one ofthe electrodes of the electrical device. When the electrode is displacedto compress the conductive spring or depresses the conductive contactplate, the other contact sheet of the wireless battery connects with theother electrodes of the electrical device causing the electrical deviceto be conducted by electrical current. When the contact electrode of theelectrical device is displaced in the opposite direction, the conductivespring moves apart from the conductive contact plate and the contactplate of the other electrode of the wireless battery snap disconnectsthe other electrode on the plane preventing the electrical device frombeing conducted by current.

In the present invention, a set of batteries is used. The battery andthe wireless battery snap must be connected together while the wholecircuit is connected in series. The number of the batteries used isdetermined by the operating voltage required by the electrical device.100101 Turning on the battery of the present invention is achieved bythe variation of the relative horizontal distance between the conductivespring and the contact plate. Two electrodes of the electrical deviceare secured in parallel on the same plane with one electrode permanentlyin contact with the conductive spring. When the electrode is displacedvertically to depress the conductive spring, the other electrode isproximate to the flat contact plate of the wireless battery snapresulting in turning on of the battery in the case of contact.Conversely, when the electrode is displaced vertically to release theconductive spring, the other electrode is moved apart from the flatcontact plate of the wireless battery snap resulting in turning off ofthe power supply.

Two sets of cylindrical socket plugs are used. The cylindrical socketplugs are connected by means of a conductive contact plate orconductors. The whole circuit is connected serially or in parallel, andthe amount of the cylindrical socket plugs of the battery is determinedby the requirement of the electrical device.

The Effects of the Present Invention are as Follows:

A wireless battery snap is provided which eliminates the inconvenienceof having protruding wires and is safer in use. Also, use of theconductive spring and contact plate eliminates the use of a switch thatreduces the production cost. The conductive spring has the functions ofpreventing vibration and stabilizing the battery which eliminates theproblem of turn-on and impact noise occurring in the case of swing ordisplacement of the electrical device due to the space in the ordinarybattery compartment.

Another effect is to extend the kinds of batteries that can be used byusers. Owing to the relatively great capacity of the battery, the lifespan of the electrical device and the power of the motor can be extendedwith a lowering in the costs of the battery.

The insulating sheet 7 isdisposed in the gap between the conductive spring 5 and the conductiveeyelet 2 of the other electrode.

An inner annular formed insulating wall 16 is provided in the electrodehole 11 on the other side of the insulating support 1. The outer annularwall 17 in the outer perimeter of the insulating support 1 is used forreceiving the insulating cover 8. The battery 9 is the type that has thetwo cylindrical button electrodes disposed on the same plane.

Two button electrodes of the battery 9 which are made of conductivematerials are disposed on the cylindrical plug 3 and socket electrode 4of the wireless battery snap. The cylindrical plug electrode 3 extendsout horizontally, inwardly 32 and outwardly 31 from the centralcylindrical inner hole 33 at the base. A straight hole 34 is formed inthe center of the base for extending through the conductive eyelet 2 andthen secured. A central straight hole 41 is formed in the cylindricalsocket electrode 4 for extending through the conductive eyelet 2 tofasten the insulating support 1, the cylindrical socket electrode 4 andthe conductive eyelet 2 together.

The cylindrical plug 3 is connected to the contact plate 6 by means ofthe conductive eyelet 2, and the contact plate 6 is secured to the flatcontact surface formed on the protruded slotted base. The othercylindrical socket plug electrode is connected to the conductive spring5 or the conductive contact plate 50 by the conductive eyelet 2.
